Which method can be used to secure sensitive data on a computer?

• A. Encrypting files
• B. Using non-secure passwords
• C. Disabling firewalls
• D. Sharing passwords with colleagues

Answer: (A)

Encrypting files is an effective method for securing sensitive data on a computer because it transforms the original information into a code that can only be read or accessed by those who have the decryption key. This means that even if unauthorized individuals gain access to the files, they will not be able to interpret the information without the correct key, thereby protecting the confidentiality of the data. Using non-secure passwords, disabling firewalls, and sharing passwords with colleagues would all compromise the security of the data rather than enhance it. Weak passwords can be easily guessed or cracked, leaving sensitive data vulnerable. Firewalls help to protect a network from unauthorized access and disabling them increases exposure to security threats. Sharing passwords can lead to unauthorized access since multiple individuals can then use the same credentials, making tracking and securing accounts more difficult. Thus, encrypting files remains the best choice for ensuring the protection of sensitive information.
